A federal judge blocked the Trump administration from subpoenaing Minnesota Governor Tim Walz and other state officials, ruling the effort was retaliation against officials who have resisted federal immigration enforcement directives. The ruling adds to a growing pattern of judicial constraints on the administration's second-term enforcement agenda — at least three federal courts have blocked similar Trump administration actions in the past 18 months. The broader legal fight centers on whether state officials can be compelled to assist federal immigration enforcement, a question with implications for sanctuary state policies nationwide.
